What door are you knocking on?
Is everyone knocking on a door? Should everyone be? Should everyone be all the time? Not sure for any of these.
What does that even mean? Does it refer to what one is seeking? Hoping will happen? Pursuing? Working towards? Exploring? Willing to consider as a possibility? A hope or pursuit that has been made public or visible?
Does anyone remember the moment while knocking on a door that it suddenly gave way? A door opening unexpectedly, against all odds, or in a different way than assumed?
Of course, this whole doors construct of life and its movement could be challenged. What other ways could we depict, understand, or allegorize the movement between one life season or reality and the next?
I would keep hypothesizing but I have to work on my knock.
